在带有 3 个按钮的 StackView 的主屏幕小部件上，小部件项目

Question

我有一个带有 StackView 的小部件布局。 在小部件项目中，我有三个按钮。 问题是：如何触发 3 个不同的事件（每个按钮一个）。

widget_layout.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/layout"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:layout_margin="8dip"
    android:background="@drawable/layout_round_corners"
    android:orientation="vertical"
    android:padding="3dp" >

    <TextView
        android:id="@+id/txtTitle"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:background="@drawable/gradient_bk_text_view"
        android:gravity="center_horizontal"
        android:padding="5dp"
        android:text="My Contacts"
        android:textColor="@color/Azure"
        android:textSize="@dimen/txt_title_size" />

    <StackView
        android:id="@+id/stack_view"
        android:layout_width="match_parent"
        android:layout_height="0dp"
        android:layout_weight="1"
        android:gravity="center"
        android:loopViews="true" />

    <TextView
        android:id="@+id/empty_view"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:background="@drawable/widget_item_background"
        android:gravity="center"
        android:padding="10dp"
        android:text="@string/empty_view_text"
        android:textColor="#ffffff"
        android:textSize="20sp"
        android:textStyle="bold" />

</LinearLayout>

和

widget_item.xml

<?xml version="1.0" encoding="utf-8"?>

        android:background="@drawable/widget_item_background"
        android:gravity="center"
        android:padding="10dp"
        android:scaleType="fitXY"

    </LinearLayout>

</LinearLayout>

在WidgetService.java 上

public RemoteViews getViewAt(int position) {
    RemoteViews rv = new RemoteViews(mContext.getPackageName(), R.layout.widget_item);

    byte[] img = mContactos.get(position).getFoto();
    Bitmap theImage = null;
    try {
        theImage = BitmapFactory.decodeByteArray(img, 0, img.length);
        rv.setImageViewBitmap(R.id.widget_item, Utils.getResizedBitmap(theImage, 400, 400));
    } catch (Exception e) {
        Log.i(TAG, "-----------------------> Image Exception: " + e.getMessage());
        rv.setImageViewResource(R.id.widget_item, R.drawable.icon_sem_foto);
    }
    rv.setTextViewText(R.id.txtWidgetNome, mContactos.get(position).getNome());

    Bundle extras = new Bundle();
    extras.putInt(StackWidgetProvider.EXTRA_ITEM_POSITION, position);
    extras.putInt(StackWidgetProvider.EXTRA_ITEM_ID, mContactos.get(position).getId());
    extras.putString(StackWidgetProvider.EXTRA_ITEM_NAME, mContactos.get(position).getNome());
    extras.putString(StackWidgetProvider.EXTRA_ITEM_TELEFONE, mContactos.get(position).getTelefone());
    extras.putString(StackWidgetProvider.EXTRA_ITEM_EMAIL, mContactos.get(position).getEmail());

    Intent fillInItemIntent = new Intent();
    fillInItemIntent.putExtras(extras);
    rv.setOnClickFillInIntent(R.id.widget_item, fillInItemIntent);
    rv.setOnClickFillInIntent(R.id.imgbtn_chamada, fillInItemIntent);
    rv.setOnClickFillInIntent(R.id.imgbtn_mensagem, fillInItemIntent);
    rv.setOnClickFillInIntent(R.id.imgbtn_email, fillInItemIntent);

    return rv;
}

在我的代码中，每次点击只会触发 ACTION_TOAST！ 我已经尝试过相同的解决方案（也在代码上）但没有结果！ 提前致谢。

所以基本上你必须做两件事才能将 onClick 行为添加到 Android App Widget 中 StackView/ListView 中的按钮。

在实现 RemoteViewService.RemoteServiceFactory 的 StackRemoteViewsFactory 的 getViewAt 函数中，为要添加函数的 id 添加 setOnClickFillingIntent() 。 例如。

 RemoteViews rv = new RemoteViews(mContext.getPackageName(), R.layout.widget__fan);
 Bundle extras = new Bundle();
 extras.putInt(TestWidget.EXTRA_ITEM, position);
 Intent fillInIntent = new Intent();
 fillInIntent.putExtras(extras);
 rv.setOnClickFillInIntent(R.id.fan_status, fillInIntent); // id of button you want to add a onClick function to.

在扩展 AppWidgetProvider 的 WidgetProvider 类的 onUpdate 函数中，添加一个 setPendingIntentTemplate()。 例如。

 Intent toastIntent = new Intent(context, TestWidget.class);
 toastIntent.setAction(TestWidget.act1);
 toastIntent.putExtra(AppWidgetManager.EXTRA_APPWIDGET_ID, appWidgetId);
 intent.setData(Uri.parse(intent.toUri(Intent.URI_INTENT_SCHEME)));
 PendingIntent toastPendingIntent = PendingIntent.getBroadcast(context, 0, toastIntent,PendingIntent.FLAG_UPDATE_CURRENT);
 rv.setPendingIntentTemplate(R.id.lview, toastPendingIntent);

现在，已经为该特定按钮设置了操作（在我的情况下为 R.id.fan_status）。 您可以在 onRecieve() 函数中添加其功能。 例如。

public void onReceive(Context context, Intent intent) {    
    if (intent.getAction().equals(act1)) {
       // Add your functionalities
    }
}
